    Back on January 8th I ordered this rifle
    http://palmettostatearmory.com/index.php/omni-16-22lr-polymer-m4-rifle-omni22.html
    It came in to my FFL earlier this week and I picked it up today :) Three weeks from order to delivery is pretty good all things considered. I also ordered a 12" free float quad rail and some Magpul MBUS sights.

    The lower is marked multi-caliber

    I am wanting to install the free float quad rail but have some questions. I heard somewhere that the barrel nut on the Chiappa upper should only be tightened down hand tight and that over tightening it can damage the plastic upper. I can't seem to loosen it with just my hands, should I order an armorer's wrench and use that to loosen it, or will that risk damaging the threads on the upper? The flash hider, front sight post and handgaurds came off pretty easily

    I also noticed that he barrel isn't threaded, but instead uses a set screw to hold the flash hider on. The OD of the end of the barrel measures exactly .500" can I just use a 1/2-28 die to thread it for use with other muzzle brakes? I know if I was going to use a suppressor I would need to take more care to make sure the threads were centered with the bore, but for use normal muzzle brakes will doing it by hand be ok?

    Unfortunately, I have nothing constructive to add, but that's pretty.

    I've got the same lower on my 5.56 AR.

    My medically retired 11B buddy was shocked when I told him it was plastic. Kinda funny he couldn't tell.

    I don't have as many rounds down range as I would like, it's still in the "break-in" phase, but I'm hitting 2.5" groups at 100 yards with a DPMS upper.

    It's a solid lower, and for a .22 LR should last forever and serve you well. Enjoy!

    Just save some pennies and get the threads done professionally to start with. Then if you, or the next owner want to put a suppressor on it, it isn't a huge hassle. It'll also be a lot less frustrating than trying to line up a die and put threads onto hard steel.

    about how much would it cost to get threaded if I already have the barrel out?

    Here is a picture of it taken apart before putting the quad rail on

    And after I put the quad rail on and put it back together

    I took it to the range today, put 300 rounds down range and had a ton of fun :) This is before realizing that .22LR is so hard to find right now. I figured .22 wouldn't be a round that would take such a big hit with the craze right now(obviously I was wrong) Anyone know where I can find .22 in stock so I can go have some more range fun?
